It's the day before launch at Cape Canaveral. Here's a timeline of events for LightSail's first day in space.

Two months. Eight and half weeks. 58 days. It's a concept almost too difficult to grasp: we are on Pluto's doorstep.

PROCYON, the mini-satellite launched with Hayabusa2, will not be able to achieve its planned asteroid flyby due to the failure of its ion engine.

Curiosity is finally on the road again! And she's never taken a more scenic route than this. Her path to Mount Sharp is taking her to the west and south, across sandy swales between rocky rises.

After investigating some flat, light and dark toned rocks around Spirit of St. Louis Crater in April, Opportunity chalked up another milestone achievement – the 4000th sol or Martian day of surface operations.

MER mission ops team members joined other engineers and scientists, some who previously worked on the MER mission, to take on the challenge of a relay marathon to celebrate Opportunity's milestone achievement.

There is one less robot exploring the solar system today. MESSENGER, which has orbited Mercury for four years, finally ran out of fuel and crashed into the planet at 17:26 UT on Thursday, April 30, 2015.

The six crew members aboard the International Space Station will have to go without a scheduled delivery of food, supplies and fuel.

An International Space Station-bound cargo craft is spinning out of control in Earth orbit following an afternoon launch from the Baikonur Cosmodrome in Kazakhstan.

In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Rosetta completed very close flybys on February 14 and March 28, taking amazing photos. But comet dust is making navigation difficult, so the mission is now keeping a respectful distance from the comet and replanning its future path.

The OSIRIS-REx team has been busy assembling and testing the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) and the Sample Return Capsule (SRC).

SpaceX's ISS-bound Dragon spacecraft is in orbit, but the drone ship landing of the company's Falcon 9 rocket was unsuccessful.

PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that launched on December 3 as a secondary payload with Hayabusa2. The mission has now selected their asteroid flyby target -- a binary asteroid named 2000 DP107 -- but is reporting a problem with their ion engines.

The Planetary Society’s LightSail spacecraft will have to wait at least two more weeks before setting sail on its maiden voyage.

Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.

SpaceX is gearing up for a second attempt to land the spent first stage of a Falcon 9 rocket on a ship in the Atlantic Ocean.

On March 24, 2015, after spending several weeks investigating some new rock types along the western rim of Endeavour Crater, Opportunity roved past 42.2 kilometers (26.2 miles) and put the first off-Earth marathon in her rear view mirror, driving the Mars Exploration Rovers mission back into the space history books.

The OSIRIS-REx mission passed another major milestone. We now have approval to build the spacecraft.
