But as more and more missions take flight, the network is getting congested. So in the near term, NASA is working to lighten the load.Atomic clocks on the crafts themselves will cut transmission time in half, allowing distance calculations with a single downlink.

They’ll jettison extra fuel, then use rocket boosters or solar sails to angle down and burn up on reentry.Launched in 1990, Hubble has been visited by astronauts four times in order to make repairs and add new instruments.Each instrument that flies on Hubble has special features that let astronomers study the heavens in different ways.Everything from student-project satellites to the New Horizons probe meandering through the Kuiper Belt depends on it to stay oriented.An ultraprecise atomic clock on Earth times how long it takes for a signal to get from the network to a spacecraft and back, and navigators use that to determine the craft’s position.When these particles knock into the atoms of aluminum that make up a spacecraft hull, their nuclei blow up, emitting yet more superfast particles called secondary radiation. They’re light and strong, and they’re full of hydrogen atoms, whose small nuclei don’t produce much secondary radiation.“You’re actually making the problem worse,” says Nasser Barghouty, a physicist at NASA’s Marshall Space Flight Center. NASA is testing plastics that can mitigate radiation in spaceships or space suits. Scientists on the Space Radiation Superconducting Shield project are working on a magnesium diboride superconductor that would deflect charged particles away from a ship.It’s a vacuum, after all; nothing to slow you down. Chemical propellants are great for an initial push, but your precious kerosene will burn up in a matter of minutes. Here’s a look at what rocket scientists now have, or are working on, or wish they had. The US Space Surveillance Network has eyes on 17,000 objects—each at least the size of a softball—hurtling around Earth at speeds of more than 17,500 mph; if you count pieces under 10 centimeters, it’s closer to 500,000 objects.After that, expect to reach the moons of Jupiter in, oh, five to seven years. Launch adapters, lens covers, even a fleck of paint can punch a crater in critical systems.Maybe we could go there.”It’s a huge, dangerous, maybe impossible project. But powerful forces conspire against you—specifically, gravity.But that’s never stopped humans from bloody-mindedly trying anyway. If an object on Earth’s surface wants to fly free, it needs to shoot up and out at speeds exceeding 25,000 mph. It cost nearly 0 million just to the Mars Curiosity rover, about a tenth of the mission’s budget, and any crewed mission would be weighed down by the stuff needed to sustain life.
