What is the 25 year rule in space?
The voluntary ISO standard also adopted the "25-year rule" for the "LEO protected region" below 2,000 km (1,200 mi) altitude that has been previously (and still is, as of 2019) used by the US, ESA, and UN mitigation standards, and identifies it as "an upper limit for the amount of time that a space system shall remain ...What happens if you stay in space for 5 years?
If you stay for a long time in space, your muscles and bones will weaken, primarily in the legs and lower back. Gravity always acts on you while you're on the earth, so even if you're not really conscious of resisting gravity, you're always using the muscles of your lower body.What will happen in space in 2035?
In this next phase, the space sector will magnify and extend its reach. By 2035, we will be living in a world where low-cost constellations of satellites make drone deliveries, autonomous vehicles and truly seamless communications everyday realities.Why are nukes banned in space?
Detonating a nuclear weapon in LEO would affect the largest number of satellites and disrupt space-based capabilities across the board. A nuclear explosion in MEO would affect navigation systems that are also used for military purposes.What is the 25 year de orbit rule?
The general guideline is that spacecraft in LEO must deorbit, also known as decay, or be placed in graveyard orbit within a maximum of 25 years after the completion of their mission (3).eSpace Webinar - Space Safety is Foundation for Reliable Space Traffic Management
How much longer will Earth be livable?
Earth will likely remain habitable for complex life for at least another 1.5 to 2 billion years, but the sun's increasing luminosity will eventually cause oceans to evaporate and complex life to end, with total uninhabitability occurring in roughly 1 to 3 billion years, though some studies suggest conditions for humans become difficult much sooner due to runaway greenhouse effects from solar energy, potentially in a few hundred million years.How long would GPS work after the apocalypse?
It would literally start degrading within hours of shutting off the Earth-based control system. The accuracy of the signals would decrease over time. While the satellites would continue to transmit signals for years, without ground control, they wouldn't know where they are and the almanac data would expire.What is the deadliest weapon on the planet?
There's no single "most dangerous" weapon, but nuclear weapons are universally considered the most destructive due to their potential for global annihilation, with the Soviet Union's Tsar Bomba being the most powerful ever tested, while modern nuclear warheads (like the U.S. W88) pose an existential threat, prompting global concern from scientists and leaders.Are guns allowed in space?
The Outer Space Treaty forbids placing weapons of mass destruction in space. Other than that handgun on the Soyuz, that's about it. That handgun is a weapon of bear or wolf destruction, not a weapon of mass destruction.How do rockets work in space if there is no oxygen?
If there is no oxygen in space, how do rockets ignite their engines? Rockets carry an oxidizer, often in the form of liquid oxygen, to burn their engine fuel. That's the fundamental difference between rockets and jets; the latter get oxygen from the air.Does the Bible say we can't go to space?
No, the Bible doesn't explicitly forbid space travel; instead, some verses suggest God gave humanity dominion over creation, implying exploration is acceptable, while others emphasize God's vastness in the heavens, with interpretations varying on whether this includes outer space or just the celestial realm. Many Christians view space exploration as a way to marvel at God's glory, aligning with the biblical idea of studying creation to praise the Creator, similar to how past scientists explored the natural world.What will hit Earth in 2030?
While some asteroids were once considered potential threats for 2030, most have been ruled out, with current tracking showing no major known asteroid impact threat to Earth in 2030, though monitoring of near-Earth objects continues, with occasional small ones passing by harmlessly or being reclassified as non-threatening as orbits are refined. Any past alerts, like for asteroid 2000 SG344, were downgraded to zero risk after better data became available, showing it would pass millions of kilometers away.What happens every 176 years?
A Once-in-a-Lifetime AlignmentCalculations reveal it is possible for a spacecraft launched in the late 1970s to visit all four giant outer planets, using the gravity of each planet to swing the spacecraft on to the next. This alignment occurs once every 176 years.
How do astronauts urinate and defecate in space?
Astronauts use specialized vacuum toilets on the ISS that use airflow instead of water to suction waste away, requiring them to secure themselves with restraints to create a seal for pooping or hold a funnel tightly for peeing. Urine is recycled into drinking water, while solid waste is dried, compressed, and stored in containers that are burned up in Earth's atmosphere on cargo ships.Who was lost in space for 311 days?
Sergei Krikalev, a Soviet cosmonaut, was "lost" in space for 311 days when the Soviet Union collapsed in 1991, extending his mission on the Mir space station due to political upheaval and budget chaos, earning him the nickname "the last Soviet citizen" as he returned to a different country. His return was delayed because the country that launched him ceased to exist, and there was no replacement crew or funds for his retrieval, forcing him to stay in orbit for twice his planned time.Is it true you age slower in space?
Yes, astronauts age slightly slower in space due to time dilation from Einstein's relativity, as their high speed (orbiting Earth) slows time for them more than the weaker gravity speeds it up, making them milliseconds younger than people on Earth after months in orbit, though the effect is tiny and biological changes mimicking aging (like bone/muscle loss) actually occur, even as time itself slows slightly for them.Is there anything illegal in space?
Weapons of mass destruction are forbidden in orbit and beyond, and the Moon, the planets, and other celestial bodies can only be used for peaceful purposes.Has anyone fired a bullet in space?
Yes. Bullets carry their own oxidising agent in the explosive of the cartridge (which is sealed, anyway) so there's no need for atmospheric oxygen to ignite the propellant.What is the temperature of outer space?
The average space temperature is approximately 2.7 kelvins (-454.8°F or -270.4°C), meaning most of space is close to empty but not entirely devoid of energy.What weapon has killed the most humans in history?
Nuclear weaponNuclear weapons are the elephant in the room when the deadliest weapons in history are being discussed.

What are the 4 noble weapons?
The "Four Noble Weapons" in Chinese martial arts refer to the foundational tools of Kung Fu: the Staff (Gùn), the Broadsword (Dāo), the Spear (Qiāng), and the Straight Sword (Jiàn), each representing different movement principles and skills, with proficiency in these four establishing a foundation for nearly any other traditional weapon.What is the oldest satellite still transmitting?
Vanguard 1 was the first satellite to have solar electric power. Although communication with the satellite was lost in 1964, it remains the oldest man-made object still in orbit, together with the upper stage of its launch vehicle.Who owns the 31 GPS satellites?
Users of Satellite Navigation are most familiar with the 31 Global Positioning System (GPS) satellites developed and operated by the United States. Three other constellations also provide similar services.Can the US turn GPS off?
GPS is owned by the U.S. government and run by the Department of Defense, or DoD. It's paid for by taxpayers and built to support both military and civilian needs. While the government has the power to turn off GPS and theoretically could, there's never been any indication that it's ever happened.
