If all goes well, the Dragon cargo ship launched on Friday will reach the space station on Sunday, April 20, to be captured by the station’s robotic arm at 7:14 am ET.
The launch originally planned for Monday was scrubbed due to a helium leak in the rocket. From an email I received from SpaceX this morning:
A launch on Friday results in a rendezvous with the space station on Sunday, April 20 and a grapple at 7:14 a.m ET.
During Monday’s launch attempt, preflight checks detected that a helium valve in the stage separation pneumatic system was not holding the right pressure. This meant that the stage separation pistons would be reliant on a backup check valve.
No issue was detected with the backup valve and a flight would likely have been successful, but SpaceX policy is not to launch with any known anomalies. We have brought the vehicle back to horizontal and are replacing the faulty valve, as well as inspecting the whole system for anything that may have contributed to the valve not working as designed.
NASA Kennedy Space Center's historic Launch Complex 39A, the site from which numerous Apollo and space shuttle missions began, is beginning a new mission as a commercial launch site.
NASA signed a property agreement with Space Exploration Technologies Corporation (SpaceX) of Hawthorne, Calif., on Monday for use and occupancy of the seaside complex along Florida's central east coast. It will serve as a platform for SpaceX to support their commercial launch activities.

For NASA's long-duration human spaceflight missions, travelers will need to recycle as much breathable oxygen in their spacecraft environments, as possible. To turn that need into a reality, NASA is seeking proposals for lightweight, safe, efficient and reliable systems for regenerating oxygen on future human exploration missions.
The first of two phases of this new NASA solicitation will consist of a detailed design, development, fabrication, and testing of an advanced oxygen recovery techn [...]
The astronauts of the International Space Station’s Expedition 39 crew focused Tuesday on preparations for a contingency spacewalk to be conducted in the next week or so. Meanwhile station program managers and SpaceX officials are working toward scheduling dates for the next launch attempt for Dragon cargo spacecraft and that contingency spacewalk, while managing all this around the planned undocking and redocking of a Russian cargo craft next week.
Monday's launch attempt of the SpaceX Dra [...]
Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin?
A new study from researchers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and the Icy Worlds team at NASA's Astrobiology Institute, based at NASA's Ames Research Center in Mo [...]
This new image from ESO’s La Silla Observatory in Chile reveals a cloud of hydrogen called Gum 41. In the middle of this little-known nebula, brilliant hot young stars are giving off energetic radiation that causes the surrounding hydrogen to glow with a characteristic red hue.
This area of the southern sky, in the constellation of Centaurus (The Centaur), is home to many bright nebulae, each associated with hot newborn stars that formed out of the clouds of hydrogen gas. The intense radiat [...]
Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute.
The climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers, even if those planets are somewhat far from their stars. And with some water remaining liquid on the surface long-term, such planets [...]
A beautiful, reddened Moon slid through dark skies on April 15, completely immersed in Earth's shadow for well over an hour. It was the year's first total lunar eclipse and was widely enjoyed over the planet's Western Hemisphere. Seen from the Caribbean island of Barbados, the dimmed lunar disk is captured during totality in this colorful skyview.
The dark Moon's red color contrasts nicely with bright bluish star Spica, alpha star of the constellation Virgo, posing only about two degrees awa [...]
