SpaceX says it wants to save NASA money, but its actions could cost taxpayers more in the end.
Orion's service module arrived in Florida, but some space industry experts question whether NASA's human spaceflight plans are realistic.
About two minutes after liftoff, the Soyuz vehicle carrying NASA astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin to orbit failed.
On February 6, 2018, I found myself shoulder to shoulder with two of my heroes: Bill Nye on the left, Buzz Aldrin on the right. Our eyes were fixed on the first vertical Falcon Heavy rocket. Figuring the world's most powerful rocket might send me flying backwards once the countdown hit zero, I gripped the railing so tightly I started to lose the feeling in my fingertips.
This Saturday, the final Delta II rocket will launch NASA's ICESat-2 spacecraft into orbit.
NASA is planning for a 30-day mission to lunar orbit in 2024.
Getting NASA out of the rocket business is more complicated than you think.
Will NASA's Space Launch System be ready to launch a Europa mission in 2022?
Vice President Mike Pence kicked off the National Space Council's first meeting today by declaring Americans will return to the Moon. Casey Dreier and Jason Davis analyze this new direction for NASA's human spaceflight program.
Last week, NASA revealed an updated design for the Space Launch System, featuring black-and-white checkerboards streaking down each of the vehicle's solid rocket boosters.
The first operational launch of the Geostationary Satellite Launch Vehicle Mark 3 rocket, or GSLV-MK3, developed by the Indian Space Research Organization (ISRO), was successfully conducted on Monday.
The countdown has begun for the first fully operational flight of the Indian Space Research Organization’s most powerful rocket to date: the Geostationary Launch Vehicle Mark 3, or GSLV-MK3.
Rocket Lab's Electron, a light-lift launcher for small satellites, is ready to make its debut test flight from a peninsula in New Zealand.
The Space Launch System and Orion won't fly until 2019, and NASA is sticking with its original plan not to include astronauts for the maiden mission. Here is a timeline of some of the programs' major twists and turns over the years.
In the second and final chapter of our series, we’ll explore what the rocket equation has to say about travel through the solar system, using the example of launching a rocket to Pluto.
Have you ever wanted to learn the fundamental physics behind one of the most basic concepts of rocket science? In part one of our two-part series, we explore the foundations of the famous rocket equation.
NASA's new heavy lift rocket is currently scheduled to launch the Orion spacecraft on a test flight next year. But all signs are pointing to a probable delay.
NASA revealed its most concrete plan yet for sending humans back into deep space, centered around a small lunar space station and a reusable transport ship to carry astronauts to Mars and back.
NASA has only flown astronauts aboard a rocket's first flight once, when John Young and Bob Crippen took space shuttle Columbia on the boldest test flight in history. What are the risks of repeating the feat for SLS?
International Space Station (ISS) project partners are inching ever closer toward an agreement to begin the development of a new human outpost in the vicinity of the Moon. If successful, the cis-lunar space station (a space station in the vicinity of the Moon) will be the largest international space project to date, influencing the direction of human space flight for decades to come.
