Researchers were greatly surprised to discover 3-million-year-old landscape beneath Greenland Ice Sheet! The finding provides strong evidence that the Greenland Ice Sheet has persisted much longer than previously known, enduring through many past periods of global warming.

The new discovery indicates that even during the warmest periods since the ice sheet formed, the center of Greenland remained stable. "It’s likely that it did not fully melt at any time," said University of Vermont geologist and lead author Paul Bierman. This allowed a tundra landscape to be locked away, unmodified, under ice through millions of years of global warming and cooling.

And liftoff! SpaceX's Falcon 9 rocket with Dragon spacecraft lifted off at 3:25 p.m. EDT from Launch Complex 40, Cape Canaveral Air Force Station, Fla. and is on its way to the International Space Station. Dragon’s twin solar arrays deployed on schedule less than 15 minutes after launch. They will allow the spacecraft to recharge its batteries on its way to the space station.

Today's Launch Site From Space! Astronaut Steve Swanson captured this view of Cape Canaveral, Florida, from the International Space Station. At Launch Complex 40, Cape Canaveral Air Force Station, SpaceX is preparing to launch its Falcon 9 rocket and Dragon spacecraft at 3:25 p.m. EDT today on its third commercial resupply mission to the space station. The Dragon is loaded with nearly 5,000 pounds of supplies and experiment hardware.

The U.S. Air Force 45th Weather Squadron predicts a 40 percent chance of favorable conditions at launch time. A launch today will send Dragon on a course to rendezvous with the station Sunday morning. The backup launch opportunity for the launch of SpaceX-3 is Saturday, April 19 at 3:02 p.m.

SpaceX's Falcon 9 rocket and Dragon were rolled to the launch pad at Cape Canaveral Air Force Station’s Space Launch Complex 40 overnight and rotated vertical at about 8 a.m. EDT. Launch is targeted for 3:25 p.m. NASA Television coverage will begin at 2:15 p.m. A launch on Friday results in a rendezvous with the International Space Station on Sunday, April 20 and a grapple at 7:14 a.m. NASA TV coverage will begin at 5:45 a.m. with berthing coverage beginning at 9:30 a.m. 

The U.S. Air Force 45th Weather Squadron predicts a 40 percent chance of favorable conditions for the launch of SpaceX-3 to the International Space Station today. There is a chance of showers and thunderstorms that could cause violations of the Thick Cloud, Lightning and Flight Through Precipitation rules. For a backup launch opportunity on Saturday the weather is 60 percent “go” with a possibility of violating the Thick Cloud, Liftoff Winds and Flight Through Precipitation rules. For a potential opportunity – if selected – on April 22, there is an 80 percent chance of favorable weather with a possibility of violating the Cumulus Cloud and Thick Cloud rules. The detailed weather forecast is below.

If needed, launch on Saturday would occur at 3:02 p.m. NASA Television coverage would begin at 2 p.m. This would be a three-day trek to the station instead of two days with grapple on Tuesday, April 22. Weather is forecast to improve to 60 percent “go” on Saturday.

Below the weather forecast is a timeline from launch through berthing.

At 9:30 a.m., NASA TV will carry a briefing from Johnson Space Center in Houston to preview a spacewalk that will be conducted by two NASA astronauts aboard the station in the coming week. The spacewalkers will replace a failed backup computer relay system on the space station's truss. 

The briefing participants are:
-- Mike Suffredini, International Space Station program manager
-- Brian Smith, International Space Station flight director
-- Glenda Brown, lead spacewalk officer

The Falcon 9 rocket, with the Dragon spacecraft on top, has been loaded with its complement of flight propellants. Countdown is progressing smoothly today and there are no technical concerns with the rocket and spacecraft. The weather remains 40 percent “go” but is improving.

An on-time liftoff this afternoon means the Dragon spacecraft will catch up to the station Sunday, April 20. The Dragon will be grappled at approximately 7:14 a.m. by Expedition 39 Commander Koichi Wakata of the Japan Aerospace Exploration Agency. He will be assisted in a backup position by NASA Flight Engineer Rick Mastracchio. The Dragon will be attached to the Earth-facing port of the station's Harmony node and will remain in place approximately one month. It is scheduled to return to Earth for a splashdown in the Pacific Ocean off the coast of Baja California May 18.

Ground controllers confirmed that our Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft impacted the surface of the moon, as planned, between 12:30 and 1:22 a.m. EDT Friday morning.

LADEE lacked fuel to maintain a long-term lunar orbit or continue science operations and was intentionally sent into the lunar surface. The spacecraft's orbit naturally decayed following the mission's final low-altitude science phase. More information:

+Fernando Falcao We also could have built a lot of homes for the homeless, or sanitation facilities for those who have none, but those aren't NASA's goals, so it's pointless for you to try and make them responsible for those types of problems. If you truly care about people's lack of food, do something about it yourself, whether that is making a donation or raising awareness of the issue; don't just complain in the comment section of some unrelated topic.

Astronauts gear up for spacewalk and launch to the space station - As work continues at the Cape Canaveral Air Force Station in Florida for Friday's 3:25 p.m. EDT launch of the SpaceX Falcon 9 rocket and the Dragon cargo craft, the crew geared up Thursday for a contingency spacewalk to replace a failed backup computer relay box on the station's truss. The 2 ½-hour spacewalk is set for Wednesday, April 23, unless SpaceX scrubs its launch attempt Friday, in which case the excursion will move up earlier to Sunday, April 20.

NASA's mission is to pioneer the future in space exploration, scientific discovery and aeronautics research. To do that, thousands of people have been working around the world and in space for more than 50 years, trying to answer some basic questions. What's out there in space? How do we get there? What will we find? What can we learn there -- or learn just by trying to get there -- that will make life better here on Earth?

NASA's work is diverse: proving flight technologies; creating capabilities for sustainable human and robotic exploration; exploring Earth, the solar system and the universe beyond; developing critical enabling technologies such as the space shuttle; and conducting science in orbit aboard the International Space Station. With NASA you can explore the universe and discover Earth.
