NASA astronauts Andrew Morgan (left) and Christina Koch (right) are suited up in US spacesuits before beginning a seven-hour spacewalk to upgrade the station's batteries, October 6, 2019. In the center, NASA Flight Engineer Jessica Meir and Commander Luca Parmitano of the European Space Agency assist.

NASA’s first all-female spacewalk is finally happening on Friday — here’s how to watch it live

Astronauts Christina Koch and Jessica Meir will exit the International Space Station together on October 18 to replace a faulty battery unit.
SpaceX, the rocket company founded by Elon Musk, plans to surround Earth with Starlink satellites and provide global high-speed, low-latency internet service from orbit.

SpaceX may want to launch 42,000 internet satellites — about 5 times more spacecraft than humanity has ever flown

Elon Musk wants to cover Earth in high-speed Starlink web access. But crushing SpaceX's competition may require tens of thousands more satellites.
This Hubble image taken October 12, 2019 is the sharpest view of the comet 2I/Borisov to date.

NASA’s Hubble space telescope just took incredible photos of a visiting comet from another star system

NASA also released a time-lapse video of the comet, 2I/Borisov, hurtling past the sun. The images show a halo of dust surrounding the alien object.
The story of NASA's "missing" Lunar Module 14 likely ended in tragedy, and perhaps a rebirth.

NASA isn’t sure what happened to one of its last Apollo moon landers. The truth is probably depressing.

Grumman Aircraft designed and built lunar modules for NASA during the Apollo program. A handful never made it to space, though.
The Kiwi Space Radar is located in the Central Otago region of the south island of New Zealand.

A new radar system will track 250,000 tiny pieces of space junk. It may help prevent snowballing collisions that could cut off our access to orbit.

Tracking tiny bits of debris in space could help us avoid a potential disaster known as a Kessler event.

11 of the biggest innovations shaping the future of spaceflight today

Private companies like SpaceX and Boeing have started to take the lead in humankind's march into space.
An artist's conception of the dust and gas surrounding a newly formed planetary system.

Earth is screaming through space at 1.3 million mph. A simple animation by a former NASA scientist shows what that looks like.

Earth orbits the sun, which orbits the center of the Milky Way galaxy, which is itself barreling through space.
The center of the Milky Way galaxy, imaged by the Spitzer Space Telescope's infrared cameras, October 9, 2019.

A NASA image shows the center of our galaxy in unprecedented detail. Expect far more revealing photos from a soon-to-launch telescope.

NASA's upcoming James Webb Space Telescope will bring "the highest-quality image ever obtained of the galactic center," one researcher said.
An artist’s impression of the massive bursts of radiation (purple) exploding from the center of the Milky Way and impacting the Magellanic Stream (the white cloud below the Milky Way spiral).

A huge explosion sliced through our galaxy just 3.5 million years ago, as human ancestors walked the Earth. Scientists think it was nuclear activity i...

NASA's Hubble telescope found traces of the explosion in a gas stream beyond the Milky Way, "dramatically" changing scientists' view of our galaxy.
A space craft named "Soyuz MS-15" takes off for the International Space Station with meat cells onboard.

Astronauts just printed meat in space for the first time — and it could change the way we grow food on Earth

A spacecraft with vials of cow cells landed at the International Space Station in September. From there, cosmonauts fed the vials into a 3D printer.
