As the James Webb Space Telescope settles into a solar orbit, another version of the satellite will soon be whizzing around Earth.

A new stamp featuring the most powerful space telescope ever built will be issued by the United States Postal Service (USPS) later this year, giving collectors of space memorabilia (or stamps!) something new to add to their collection, and letter writers something to stick on their envelopes.

“Celebrate NASA’s remarkable James Webb Space Telescope, the largest and most complex telescope ever deployed in space, capable of peering directly into the early cosmos and studying every phase of cosmic history,” the USPS said in a message announcing the new stamp.

Ex-NASA astronaut says we must fix Earth’s big problems before we colonize other planets.


He tells Inverse that humans should seek to colonize distant planets. But before that happens, he acknowledges the tremendous amount of work that needs to be done on Earth first.

“We need to spread human presence throughout the Solar System and beyond, but we need to do it as ambassadors of a thriving planet,” Garan says. “We can’t do it as refugees escaping environmental disaster.”

The comments come as figures like SpaceX CEO Elon Musk and Blue Origin founder Jeff Bezos call on humanity to establish permanent settlements in space. Musk has repeatedly claimed he wants to establish a city on Mars by 2050, while Bezos wants to build giant, floating cities in Earth’s orbit.

Neil deGrasse Tyson gives his opinion on Elon Musk buying Twitter. Should Elon Musk be spending his time on Twitter or getting us to Mars? What does Neil deGrasse Tyson think of Mars as a backup plan for humanity? Is Neil deGrasse Tyson concerned about Elon Musk’s new policies?

NASA has an ambitious plan to bring a piece of Mars back to Earth for study. Called the Mars Sample Return mission, the idea is to send a robotic team consisting of a lander, rover, and an ascent vehicle to the red planet to pick up samples being collected and sealed in tubes by the Perseverance rover. These samples will then be launched off the Martian surface and into orbit, where they’ll be collected and brought back to Earth.

If that sounds complicated, it is. NASA is working on some of the hardware required for this ambitious long-term mission, and recently the agency tested out a new design for the Earth Entry System vehicle which will carry the sample through our planet’s atmosphere and to the surface. And its test was a dramatic one — dropping a model of the vehicle from 1,200 feet and seeing if it survived.

The test was focused on the vehicle’s areoshell, testing out one possible design for the shell which has to protect the delicate electronics and sample inside from the heat and forces of passing through Earth’s atmosphere. To do this, the test was performed at the Utah Test and Training Range, where a helicopter ascended with a model of the vehicle and areoshell, called a Manufacturing Demonstration Unit (MDU), that was covered in sensors and measures 1.25 meters across. The MDU was then dropped by the helicopter and its descent was recorded. Coming from an altitude of 1,200 feet, the MDU reached the speeds that would be engineers think are equivalent to a sample landing mission.
