  • While Earth’s climate has changed throughout its history , the current warming is happening at a rate not seen in the past 10,000 years.
  • According to the Intergovernmental Panel on Climate Change ( IPCC ), "Since systematic scientific assessments began in the 1970s, the influence of human activity on the warming of the climate system has evolved from theory to established fact." 1
  • Scientific information taken from natural sources (such as ice cores, rocks, and tree rings) and from modern equipment (like satellites and instruments) all show the signs of a changing climate.
  • From global temperature rise to melting ice sheets, the evidence of a warming planet abounds.

The rate of change since the mid-20th century is unprecedented over millennia.

Earth's climate has changed throughout history. Just in the last 800,000 years, there have been eight cycles of ice ages and warmer periods, with the end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

The current warming trend is different because it is clearly the result of human activities since the mid-1800s, and is proceeding at a rate not seen over many recent millennia. 1 It is undeniable that human activities have produced the atmospheric gases that have trapped more of the Sun’s energy in the Earth system. This extra energy has warmed the atmosphere, ocean, and land, and widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred.

Earth-orbiting satellites and new technologies have helped scientists see the big picture, collecting many different types of information about our planet and its climate all over the world. These data, collected over many years, reveal the signs and patterns of a changing climate.

Scientists demonstrated the heat-trapping nature of carbon dioxide and other gases in the mid-19th century. 2 Many of the science instruments NASA uses to study our climate focus on how these gases affect the movement of infrared radiation through the atmosphere. From the measured impacts of increases in these gases, there is no question that increased greenhouse gas levels warm Earth in response.

Scientific evidence for warming of the climate system is unequivocal.

Intergovernmental Panel on Climate Change

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly 10 times faster than the average rate of warming after an ice age. Carbon dioxide from human activities is increasing about 250 times faster than it did from natural sources after the last Ice Age. 3

The Evidence for Rapid Climate Change Is Compelling:

Global Temperature Is Rising

The planet's average surface temperature has risen about 2 degrees Fahrenheit (1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activities. 4 Most of the warming occurred in the past 40 years, with the seven most recent years being the warmest. The years 2016 and 2020 are tied for the warmest year on record. 5 Image credit: Ashwin Kumar, Creative Commons Attribution-Share Alike 2.0 Generic.

The Ocean Is Getting Warmer

The ocean has absorbed much of this increased heat, with the top 100 meters (about 328 feet) of ocean showing warming of 0.67 degrees Fahrenheit (0.33 degrees Celsius) since 1969. 6 Earth stores 90% of the extra energy in the ocean. Image credit: Kelsey Roberts/USGS

The Ice Sheets Are Shrinking

The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 279 billion tons of ice per year between 1993 and 2019, while Antarctica lost about 148 billion tons of ice per year. 7 Image: The Antarctic Peninsula, Credit: NASA

Ocean Acidification Is Increasing

Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30%. 13 , 14 This increase is due to humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the ocean. The ocean has absorbed between 20% and 30% of total anthropogenic carbon dioxide emissions in recent decades (7.2 to 10.8 billion metric tons per year). 1 5 , 16 Image credit: NOAA

2. In 1824, Joseph Fourier calculated that an Earth-sized planet, at our distance from the Sun, ought to be much colder. He suggested something in the atmosphere must be acting like an insulating blanket. In 1856, Eunice Foote discovered that blanket, showing that carbon dioxide and water vapor in Earth's atmosphere trap escaping infrared (heat) radiation. In the 1860s, physicist John Tyndall recognized Earth's natural greenhouse effect and suggested that slight changes in the atmospheric composition could bring about climatic variations. In 1896, a seminal paper by Swedish scientist Svante Arrhenius first predicted that changes in atmospheric carbon dioxide levels could substantially alter the surface temperature through the greenhouse effect. In 1938, Guy Callendar connected carbon dioxide increases in Earth’s atmosphere to global warming. In 1941, Milutin Milankovic linked ice ages to Earth’s orbital characteristics. Gilbert Plass formulated the Carbon Dioxide Theory of Climate Change in 1956.

Safety Culture

Nasa safety culture...it's in our dna.

Safety Culture’s mission at NASA is to create an environment where everyone works safely, feels comfortable communicating safety issues, learns from mistakes and successes, feels confident balancing challenges and risks while keeping safety in the forefront, and trusts that safety is a priority.

NASA’s Safety Culture Model is based on five criteria, or factors. Click on the buttons below to learn more about each of the five factors, and the DNA analogy that inspired the program's logo.

"Yes, If" Program

The “Yes, If” recognition coin is emblematic of the culture we would like to promote at NASA. When asked, “Is this possible?” our response should be, “Yes, if…” instead of “No, because….” Recipients of the “Yes, If” coin exemplify the spirit of ingenuity, creativity and commitment to safety that the agency was built upon. We invite you to nominate a NASA colleague who you believe has earned the “Yes, If” coin, which will be presented by the chief of Safety and Mission Assurance. The recognition coin was developed by Safety Culture Program Manager Tracy Dillinger for former Chief of Safety and Mission Assurance Bryan O’Connor.

Caught Doing Right

The Caught Doing Right initiative celebrates the NASA family’s commitment to practicing proper safety procedures. All too often we are quick to point out when our colleagues are being careless with safety, and although it's important to correct unsafe behavior, we should put equal emphasis on those who faithfully incorporate safety measures into their daily work.

What You Can Do

When you see an employee or group working safely

  • Take a photo
  • Submit your photo and complete the form by using the "Submit Photos" button

The photos, or "safies," can be accessed by any NASA employee or contractor within the NASA firewall.

By posting your “safies” on this site, you are not only sharing your commitment to safety with the rest of the agency, but sharing great work practices with them as well.

The Bottom Line

At the end of the year, a team of NASA safety professionals will assess the "safies" and decide on one to feature on a poster for all NASA centers. Be a part of celebrating your team's outstanding safety practices while encouraging others to do the same agencywide.

Assessments

The NASA Office of Safety and Mission Assurance (OSMA), along with subject matter experts from each of the NASA centers, developed the NASA Safety Culture Survey. It is designed to provide center directors with a tool to identify and correct latent organizational conditions that may lead to accidents and implement strategies to improve safety. The surveys are distributed to each center every three years and questions will vary for each round.

Each survey lists general questions, along with center-specific questions. Below are general questions from Round 1, Round 2, Round 3, Round 4, Round 5 and Round 6 of the survey.

Change Management

Feedback collected from the latest round of Safety Culture Surveys revealed an opportunity to enhance NASA’s ability to adapt to change. While the agency scored highly in most categories, the “people in our organization manage change well” question showed room for improvement. The following SATERN courses provide training on how to accept, communicate and react to change positively across the agency or specifically at your center.

Important Reports

A key part of NASA's Safety Culture is learning from our mistakes. It is only by assessing our mishaps that we are able to learn from them and move toward a better and safer future. Below are key agency mishap reports that provide important information that can benefit safety professionals both within the agency and beyond.

SSME 0523 Failure Investigation Final Report

June 16, 2000.

Space Shuttle Main Engine (SSME) 0523 was assembled as a unique development engine for a series of tests to demonstrate safe operation of the Pratt & Whitney High Pressure Fuel Turbopump (HPFTP/AT) at the High Pressure Fuel Turbine discharge temperature redline values. During the assembly of SSME 0523, Permacel P-670 tape was introduced into the fuel system during some “hands-on” process. The tape contamination went unnoticed and was left in the fuel system during the remainder of assembly and pretest activities. On June 16, 2000, a test of SSME 0523 was conducted at Stennis Space Center. During the test, the tape contamination debris set off a series of events that caused the first stage blades to fail. Post incident inspection of the engine revealed significant hardware damage to the HPFTP/AT with less significant damage to the powerhead and Main Combustion Chamber. There was no facility damage and no personnel were injured.

Rogers Commission Report (Challenger)

Jan. 28, 1986.

The consensus of the Commission and participating investigative agencies is that the loss of the Space Shuttle Challenger was caused by a failure in the joint between the two lower segments of the right Solid Rocket Motor.  The specific failure was the destruction of the seals that are intended to prevent hot gases from leaking through the joint during the propellant burn of the rocket motor.  The evidence assembled by the Commission indicates that no other element of the Space Shuttle system contributed to this failure. 

Return to Flight Task Group Report

The Columbia Accident Investigation Board (CAIB) elected to delve deeper in the accident than simply determining the physical cause. It was obvious to the board very early on that there was an underlying problem with leadership, management and culture at NASA, specifically within the Space Shuttle Program. The CAIB released the first volume of its final report, containing 29 specific recommendations for changes to the vehicle, to the Space Shuttle Program and to NASA in general. Among those recommendations were 15 that the accident board believed should be implemented prior to returning the Space Shuttle to flight. 

Helios Mishap Report

June 26, 2003.

The Helios Prototype HP03 vehicle was a remotely piloted aircraft designed for long-duration flight. On June 26, 2003, HP03-2 took off from the Navy’s Pacific Missile Range Facility, Kauai, Hawaii. The aircraft encountered turbulence and morphed into an unexpected, persistent, high-dihedral configuration. The aircraft became unstable and its design airspeed was subsequently exceeded, causing the wing leading edge to fail and the solar cells and skin on the upper surface of the wing to rip off. The aircraft impacted the ocean and was destroyed.

Glory Mishap Investigation Results

March 4, 2011.

The Glory spacecraft was a NASA satellite mission launched March 4, 2011, as the primary payload aboard an Orbital Science Corporation Taurus XL T9 launch vehicle at Vandenberg Air Force Base, California. The fairing failed to separate as planned, and the additional mass of the fairing caused the trajectory to deviate and the vehicle failed to reach orbital velocity. The vehicle reentered the atmosphere and likely broke up or burned up, or both. 

Genesis Mishap Investigation Board Report

Sept. 8, 2004.

Genesis was one of NASA’s Discovery missions, and its purpose was to collect samples of solar wind and return them to Earth. Launched on Aug. 8, 2001, Genesis was to provide fundamental data to help scientists understand the formation of our solar system. On Sept. 8, 2004 the Genesis sample return capsule drogue parachute did not deploy during entry, descent and landing operations. After the point of expected drogue deployment, the sample return capsule began to tumble and impacted the test range.

DART Mishap Investigation Results

April 15, 2005.

On April 15, 2005, the Demonstration of Autonomous Rendezvous Technology (DART) spacecraft was launched from Vandenberg Air Force Base, California. DART was designed to rendezvous with and perform a variety of maneuvers in close proximity to the Multiple Paths, Beyond-Line-of-Sight Communications (MUBLCOM) satellite. Approximately 11 hours into what was supposed to be a 24-hour mission, DART detected that its propellant supply was depleted. Although it was not known at the time, DART had actually collided with MUBLCOM.

CONTOUR Mishap Investigation Board Report

The Comet Nucleus Tour, CONTOUR, is part of the NASA Discovery series of solar system exploration satellites. Launched on July 3, 2002, CONTOUR was intended to encounter at least two comets and perform a variety of investigations and analyses of the comet material. It remained in an eccentric Earth orbit until Aug. 15, 2002, when it left orbit and began the transit to the comet Encke. The mission design did not provide for telemetry coverage during the solid rocket motor burn and no provision was made to observe the burn optically. CONTOUR was programmed to re-establish telemetry contact with the ground following the burn. However, no signal was received. Active attempts to contact CONTOUR were unsuccessful. On Aug. 16, 2002, limited ground observations identified what appeared to be three separate objects on slightly divergent trajectories near but behind CONTOUR’s expected position. Further attempts to contact CONTOUR were made through Dec. 20, 2002, when NASA and Johns Hopkins University’s Applied Physics Laboratory concluded that the spacecraft had been lost.

Columbia Accident Investigation Board Report

Feb. 1, 2003.

The Columbia Accident Investigation Board’s independent investigation into the Feb. 1, 2003, loss of the Space Shuttle Columbia and its seven-member crew lasted nearly seven months. The physical cause of the loss of Columbia and its crew as a breach in the Thermal Protection System on the leading edge of the left wing, cause by a piece of insulating foam which separated from the left bipod ramp section of the External Tank at 81.7 seconds after launch, and struck the wing. The organizational causes of this accident are rooted in the Space Shuttle Program’s history and culture, including the original compromises that were required to gain approval for the Shuttle, subsequent years of resource constraints, fluctuating priorities, schedule pressures, mischaracterization of the Shuttle as operational rather than developmental, and lack of an agreed national vision for human space flight. 

Apollo 204 Review Board Final Report

Jan. 27, 1967.

On Jan. 27, 1967, tragedy struck the Apollo program when a flash fire occurred in command module 012 during a launch pad test of the Apollo/Saturn space vehicle being prepared for the first piloted flight, the AS-204 mission. Three astronauts died in this tragic accident. A seven-member board conducted a comprehensive investigation to pinpoint the cause of the fire. The final report presented the results of the investigation and made specific recommendations that led to major design and engineering modifications, and revisions to test planning, test discipline, manufacturing processes and procedures, and quality control. The AS-204 mission was redesignated Apollo I in honor of the crew.

Dr. Tracy Dillinger is the manager for three programs: Safety Culture, Human Factors in Mishap Investigations and Human Reliability Assessment at NASA Headquarters (HQ). Dillinger is the chair of the Safety Culture Working Group and is responsible for the NASA Safety Culture Survey, Safety Culture courses and NASA Organizational Safety Assessments (OSA).

Dillinger received the NASA HQ Exceptional Performer Award in 2013. She came to NASA in 2011 after 21 years in the United States Air Force (USAF), when she retired as lieutenant colonel. Dillinger was stationed at USAF Safety Center HQ as the chief of the Safety Assessment Division from 2005 to 2008, and was the USAF chief of Aviation Psychology from 1998 to 2008. Earlier, she developed and instituted the OSA program and the Air Force Culture Assessment Safety Tool as safety prevention tools for leadership.

In 2006, she was awarded the USAF Chief of Staff Individual Safety Award for her record-breaking contributions to reducing mishap rates while ensuring mission success. Dillinger has expertise in pilot personality, witness interviewing, human factors, safety culture and organizational dynamics.

She conducted human factors portions of USAF investigations, developed a witness interview guide for use by investigation teams published in Air Force guidance, and spearheaded assessment efforts to identify risks and hazards imbedded in USAF organizations.

As USAF major, Dillinger was a member of the Columbia Accident Investigation Board in 2003 and the Space Shuttle Independent Assessment Team in 1999.

Dillinger received a Bachelor of Arts degree in psychology and a Bachelor of Arts degree in dance from the University of Iowa, a Master of Art in counseling psychology from the University of Iowa, a Doctor of Psychology degree in clinical psychology from the Chicago School of Professional Psychology (CSPP), a Post-Doctoral Fellowship from the University of Illinois in aviation psychology in 2003, and an Honorary Doctor of Psychology degree in business and organizational psychology from CSPP in 2006.

She has taught and conducted human factors investigations, organizational assessments, and witness interviewing; authored several articles on these subjects; and has held a license in clinical psychology for the past 20 years.

The DNA Analogy

Think of NASA’s Safety Culture as the organization’s DNA. Just as DNA contains the genetic instructions that guide the development and function of every living organism, Safety Culture guides and defines safety within NASA. The NASA Safety Culture logo is designed as a DNA strand consisting of five factors to remind everyone of the importance of safety as a component of NASA work life.

Each factor in the DNA model is dependent upon the others. If one component is missing, the entire system will fail. That’s why everyone — from the newest technician to top NASA leadership — should take an active role in the agency’s safety.

Everyone Does Their Part

An Engaged Culture ties together the other four cultures. Regardless of status or occupation, all NASA employees actively participate in safely accomplishing the agency’s mission. The key is having engaged leaders and employees who demonstrate they value safety and get involved.

We Learn From Our Successes and Mistakes

In a Learning Culture, employees collect, assess and share information, both formally and informally. That includes continuing education programs such as SATERN and the Safety and Mission Assurance Technical Excellence Program, as well as resources on the NASA Engineering Network and NASA Safety Center websites. It is important for employees to learn from their experiences and apply that knowledge to their jobs.

We Change To Meet New Demands

A Flexible Culture is one that builds in resilience from the beginning. It enables an organization to adapt to unforeseen developments and make changes based on incoming trend information. It also allows an organization to push past obstacles when something new or different happens. In a Flexible Culture, operations aren’t disrupted by additional demands, but continue to operate in a steady state to successfully complete the mission.

We Treat Each Other Fairly

A Culture that is Just balances the need for discipline when warranted, with rewards when earned. People clearly understand acceptable and unacceptable behaviors. There’s a sense of fairness in how business is conducted for everyone. In a Just Culture, those in authority do not “shoot the messenger” for bringing up safety concerns.

We Report Our Concerns

In a Reporting Culture, everyone is encouraged to report safety concerns. An atmosphere of trust exists between leadership and employees, with employees knowing that important information will be heard and acted upon appropriately. No one should ever be afraid to speak up; it could save a life.

NASA ambassador to give free presentation on Staten Island: ‘The Mysteries of the Sun’

  • Published: Mar. 29, 2024, 10:31 a.m.

Solar Eclipse Presentation

Harold Kozak, a NASA solar system ambassador and a retired astronomy professor, will lead a free presentation, “The Mysteries of the Sun,’' on Saturday, April 6, at the Clay Pit Ponds State Park Preserve. Here, Staten Island children view the solar eclipse in 2017. (Staten Island Advance/ Jan Somma-Hammel) Staff-Shot

STATEN ISLAND, N.Y. — A presentation about the sun and the rare April 8 total solar eclipse will be held on Saturday, April 6, at the Clay Pit Ponds State Park Preserve, Charleston.

Harold Kozak, a NASA solar system ambassador and a retired college astronomy professor, will lead the free presentation, “The Mysteries of the Sun,’' in the Clay Pit Ponds Interpretive Center, 2351 Veterans Rd. West, at 2 p.m.

It is appropriate for all ages.

On April 8, the moon will pass between the sun and Earth during an historic solar eclipse , visible across North America.

New York state has several cities in the path of totality , which means hundreds of thousands of people are expected to visit to see the phenomenon. Those cities include Niagara Falls, Buffalo and Rochester.

During the free event, Kozak will discuss the sun and share details about what to expect on April 8. He’ll also share his knowledge about the sun and point out interesting features about it.

Free NASA eclipse glasses for safely viewing the April 8 event will be available, along with other NASA souvenirs, Kozak said.

He added that Staten Islanders can expect most of the sun to be blocked by the moon, but it won’t be a total eclipse.

CAUTION URGED

“It’s very exciting to see it,’' said Kozak, a Great Kills resident, stressing the importance of people viewing the eclipse safely, while protecting their eyes with special eclipse glasses. Not doing so is very dangerous, he said.

“It’d be very easy for you to look up at the sun, because it’ll be hidden by the moon, but that’s when you don’t look,’' he said. “If you look at the sun during an eclipse, the radiation from the sun will go through the pupil of your eye ... and you’ll burn out your retina.”

The American Astronomical Society Solar Eclipse Task Force recently stated that counterfeit and fake eclipse glasses are now polluting the marketplace.

Here are three solar eclipse glasses, approved by the AAS, sold on Amazon.

LUNT SOLAR 5 Pack Premium Eclipse Glasses, AAS Approved 2024 Solar Glasses — $14.95

Solar Eclipse Glasses AAS Approved 2024 - Made in the USA CE and ISO Certified Safe Shades for Direct Sun Viewing (2 Pack) — $14.99

Medical king Solar Eclipse Glasses AAS Approved 2024 (10 Pack) CE and ISO Certified Safe Shades for Direct Sun Viewing — $14.99

Kosak said he’ll also ask a host of trivia questions about the sun. (We’ll keep those classified, to prevent cheating.) A NASA lecturer for more than 20 years and a retired Wagner College professor, Kozak said the trivia is always the best part.

“It gives them a chance to show how smart they are,’' he said.

TIMING OF THE ECLIPSE

On April 8, the path of totality will start in Mexico and move across Texas, Oklahoma, Arkansas, Missouri, Illinois, Indiana, Ohio, New York, Pennsylvania, Vermont, New Hampshire and Maine, before heading out over the North Atlantic. Small portions of Kentucky, Michigan and Tennessee will also experience almost the entirety of the eclipse.

According to NASA’s interactive map that traces the path of the eclipse , Staten Island should have full sun until 2:10 p.m. and will have totality, when the sun is nearly completely blocked, at 3:25 p.m. Full sun will return at 4:36 p.m. Staten Island should experience 89.5% totality, according to the NASA map.

Registration for the presentation is required, as seating is limited to 100 guests.

Jeff Bezos's Blue Origin passes 4 key milestones for its $172 million NASA contract to build a new space station

  • NASA awarded Blue Origin $172 million to develop a space station for both astronauts and tourists.
  • The space station, called Orbital Reef, will need to be able to support human life. 
  • Recently, Blue Origin passed four milestones in helping prove Orbital Reef is well on its way.

Insider Today

The International Space Station won't be around forever, and NASA is pouring hundreds of millions of dollars into its potential replacements.

One promising candidate is Orbital Reef — a joint venture between Jeff Bezos's space company Blue Origin and Sierra Space.

On Wednesday, NASA reported that Orbital Reef passed four key milestones for some of its most crucial technology, including a system to recycle future astronauts' and tourists' urine.

"These milestones are critical to ensuring that a commercial destination can support human life," Angela Hart, manager of NASA's Commercial Low Earth Orbit Development Program, said in NASA's announcement.

The milestones involved passing a series of tests on Orbital Reef's regenerative system. This system will provide clean air and water for humans to breathe and drink while on the space station.

Some of the tests included the system's ability to remove impurities from the air, recover urine for recycling, and maintain a water tank, NASA reported.

The ISS has a similar system that recycles water and oxygen from, as NASA puts it, "normal human activities" — a.k.a mostly breathing, sweating, and peeing. That's right, the system turns pee into drinking water .

Related stories

"Before you cringe at the thought of drinking your leftover wash water and your leftover urine , keep in mind that the water that we end up with is purer than most of the water that you drink on a daily basis at home," said former ISS Commander Chris Hadfield in a 2013 video .

In fact, astronauts on the ISS have been drinking each other's crystal-clean recycled urine for about 15 years, and for good reason. It helps reduce the amount of water NASA would need to launch into space to keep astronauts alive, thereby cutting launch costs and saving money.

Blue Origin's future space station

NASA awarded Blue Origin and Sierra Space $172 million as part of its goal to develop commercialized, American-led space stations in low-Earth orbit that could replace the ISS after it retires.

These replacements will be a place where NASA can continue to send its astronauts, leasing its own quarters and laboratory space. However, because commercial companies would own the stations, they can also be open to space tourists.

"Think spacious modules with large windows to view Earth, our blue origin, while experiencing the thrill of weightlessness in complete comfort," Blue Origin states on its website .

NASA is handing the next generation of space stations over to commercial companies because it has bigger priorities that need funding. It costs NASA about $3 billion per year to maintain the ISS program, right now.

"The agency is committed to continuing to work with industry with the goal having one or more stations in orbit to ensure competition, lower costs, and meet the demand of NASA and other customers," Hart said in a NASA statement in January.

Without the ISS, that will free up NASA's budget to focus its efforts on establishing a permanent human presence on the moon , including a space station in lunar orbit and a base on the lunar surface, via its Artemis missions .

"Overall, we projected that total Artemis costs will reach $93 billion between 2012 and 2025," George Scott, NASA's acting inspector general said during a government hearing in January adding that this didn't include the cost of launches, which will be about $4.2 billion per launch for the first four Artemis missions.

Eventually, NASA hopes to channel its budget toward sending astronauts to Mars.

The ISS is on its way out already

It's not just the money. The ISS is aging anyway. Cracks have appeared on one Russian module . Another section has been leaking air . In recent years the station has also experienced toilet failure, mysterious temperature variation, and an oxygen-supply system breakdown.

The Biden administration has committed to keep the ISS running through at least 2030. By then, NASA aims to already have made the transition to at least one privately owned space station. If all goes according to plan, the empty and decommissioned ISS will push itself into Earth's atmosphere and burn up as it plummets toward the ocean.

So there's still some time to save up to catch a ride to Orbital Reef. Ticket costs are not available, yet. For reference, a trip to skim the edge of space for just a few minutes via Blue Origin's New Shepard rocket can cost tens of millions of dollars .
