The agency must take a realist attitude to what can be done with little money, Bolden said.
After a day of rest, active region 1748 unleashed class-M1.3 and M3.2 flares on May 16th and 17th, 2013. This same storm blasted 4 X-class flares between May 13 and 15.
A new 65-foot-wide impact crater is the result.
The X-38 research vehicle touches down on Rogers Dry Lakebed.
A NASA moon monitoring telescope captured the blast, which could be seen by the naked eye on Earth, on March 17th, 2013. The object was the size of a small boulder and may be part of a meteor swarm that also flew past Earth.
In 'After Earth,' humanity is faced with a choice: Leave the planet, or die off trying to remain on it.
Images of electric spacecraft, which have explored the moon, Mars and beyond.
What we can learn from the greatest scientific mistakes in history.
The May 31 flyby of 1.7-mile-long 1998 QE2 poses no threat to Earth.
Opportunity passed the Apollo 17 moon buggy, which covered 22.21 miles back in 1972.
The new spacecraft will aid the network of navigation satellites.

By 2015 there'll be something green in space, and it won't be aliens!
Astronauts on the ground and in space spoke with three actors from 'Star Trek Into Darkness' today during a NASA-sponsored Google+ Hangout.
The mountains of the moon are visible for those that wish to see them this month.
NASA's Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) will study asteroid Bennu. It will launch in 2016, arrive at the asteroid in 2018 and a minimum of 2 ounces of it will be returned 5 years later.
Inspiration Mars may use a SpaceX rocket, a pair of ULA boosters, or NASA's SLS.
Astronomer Geoff Marcy tweaked W.H. Auden's poem to grieve for the troubled Kepler Space Telescope.
The Space Shuttle Atlantis departs the Mir Russian Space Station.
NASA Astronaut Karen Nyberg is a flight engineer on the Expedition 36/37 crew and in her down time will be hard at work with the fabric and thread she is bringing along. She is scheduled to launch to the ISS aboard a Soyuz TMA-09M on May 28th, 2013.
Asteroid 1998 QE2 is about 1.7 miles in size and makes an excellent target for radar imaging. It will pass no closer than ~3.6 million miles, but is close enough for the Goldstone and Arecibo telescopes to resolve features as small as 12 feet across.

What heats gas near supermassive black holes at the centre of galaxies? Astronomers have looked at the centre of our Galaxy, the Milky Way, with ESA's Herschel Space Observatory and discovered a rich variety of molecules at surprisingly high temperatures - up to 1000 K. The new data suggest that the molecular gas is heated up by shocks, in addition to ultraviolet radiation from massive stars close to the Galactic Centre. Shocks develop in the gas as the material surges towards Sagittarius A*, the region harbouring the supermassive black hole at the heart of the Milky Way.
Report for the period 6 January to 2 February 2013
This reporting period covers four weeks of Venus Express operations, from 6 January to 2 February 2013, and includes the continuation of the fourteenth occultation season, the start of the twenty-third eclipse season, and start of the Venus surface imaging campaign.
The Director of Science and Robotic Exploration intends to define, in the course of 2013, the science themes and questions that will be addressed by the next two Large (L-class) missions in the Cosmic Vision 2015-2025 plan, "L2" and "L3", currently planned for a launch in 2028 and 2034, respectively. This process starts with a consultation of the broad scientific community, in the form of the current Call, soliciting White Papers to propose science themes and associated questions that the L2 and L3 missions should address. The submission deadline for White Papers is 24 May 2013, 12:00 CEST (noon).
Report for period 5 to 27 February 2013
Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet assembly is common in clusters, say researchers.
Report for period 6 December 2012 to 4 February 2013Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
For the first time, scientists have resolved the detailed structure of the core region where magnetic reconnection takes place in the magnetosphere of Earth using unprecedented wave measurements. The study, based on data from ESA's Cluster mission, has mapped different types of electrostatic waves in this region. The waves trace populations of plasma particles that are involved in the different stages of a magnetic reconnection event.
Report for the period 9 December 2012 to 5 January 2013
This reporting period covers four weeks of Venus Express operations, including the start of the fourteenth occultation season, end of the tenth Atmospheric Drag Experiment campaign, and pericentre altitude raising using four orbit correction manoeuvres.
The liquid helium coolant that enabled instruments on board the Herschel space observatory to collect extraordinary images and spectra has finally run out. Launched in 2009, the ESA mission collected unprecedented data of the cool as well as of the distant Universe. Herschel's observations have exceeded expectations, enabling scientists to learn more about how stars form, about the rates of star formation in galaxies across the cosmos, and about the origin and presence of water in different celestial bodies. While observations have come to an end and the spacecraft is to be propelled to a stable parking orbit around the Sun, where it will remain indefinitely, the science mission will continue for several years with many discoveries still to be made in the treasure trove of images and spectra collected by the observatory.
Report for the period 6 to 14 June 2011This report covers nine days of Rosetta mission operations. The main activities were the spin-up of the spacecraft and entry into deep-space hibernation mode. The spacecraft will remain in this state until 20 January 2014 when the hibernation exit sequence will be initiated. The next Rosetta status report will be issued towards the end of January 2014.
