Washington: For the first time in almost 40 years, NASA has completed all steps needed to clear a critical design review (CDR) for the most powerful rocket ever built that will take humans to deeper space missions, including Mars.

The agency’s Space Launch System (SLS) is the first vehicle designed to meet the challenges of the journey to Mars and the first exploration class rocket since the Saturn V.

SLS will launch America into a new era of exploration to destinations beyond Earth’s orbit.

“We have successfully completed the first round of testing of the rocket’s engines and boosters and all the major components for the first flight are now in production,” explained Bill Hill, deputy associate administrator of NASA’s Exploration Systems Development Division.

“This review gives us confidence that we are on the right track for the first flight of SLS and using it to extend permanent human presence into deep space,” he added.

This review is the last of four reviews that examine concepts and designs.

The next step for the programme is design certification, which will take place in 2017 after manufacturing, integration and testing is complete.

The design certification will compare the actual final product to the rocket’s design.

The final review, the flight readiness review, will take place just prior to the 2018 flight readiness date.

“This is a major step in the design and readiness of SLS,” added John Honeycutt, SLS programme manager.

The core stage of SLS, towering more than 200 feet tall and with a diameter of 27.6 feet, will carry cryogenic liquid hydrogen and liquid oxygen fuel for the rocket’s four RS-25 engines.

NASA recently completed the first developmental test series on the RS-25 engines.

NASA’s Kepler Discovers Nearly 100 New Exoplanets

NASA researchers found that some of the signals were caused by multiple star systems or noise from the spacecraft

  • NASA’s Kepler has discovered nearly 100 new exoplanets
  • Some of the planets discovered are as large as Jupiter
  • NASA has also found planet which orbits very bright stars

An international team of scientists have confirmed the discovery of nearly 100 new exoplanets — planets located outside our solar system.

The discovery was based on data from the second mission of NASA’s Kepler Space Telescope or K2 released in 2014.

K2 searches for exoplanet transits by registering dips in light caused by the shadow of an exoplanet as it crosses in front of its host star.

NASA researchers found that some of the signals were caused by multiple star systems or noise from the spacecraft.

But they also detected planets that range from sub-Earth-sized to the size of Jupiter and larger.

One of the planets detected was orbiting a very bright star.

“We validated a planet on a 10-day orbit around a star called HD 212657, which is now the brightest star found by K2 missions to host a validated planet,” said lead author Andrew Mayo, a doctoral student at the National Space Institute (DTU Space) at the Technical University of Denmark.

For the study, appearing in the Astronomical Journal, the team started out analyzing 275 candidates of which 149 were validated as real exoplanets.

In turn 95 of these planets have proved to be new discoveries, Mayo said.

The Kepler spacecraft was first launched in 2009 to hunt for exoplanets in a single patch of sky, but in 2013 a mechanical failure crippled the telescope.

However, astronomers and engineers devised a way to repurpose and save the space telescope by changing its field of view periodically. This solution paved the way for the follow up K2 mission.

Adding the newly discovered exoplanets brings the total number of exoplanets by K2 mission to almost 300, the study said.

The first planet orbiting a star similar to our own Sun was detected only in 1995. Today some 3,600 exoplanets have been found, ranging from rocky Earth-sized planets to large gas giants like Jupiter. IANS
