The Neutron star Interior Composition ExploreR (NICER) is a future NASA Explorer program mission dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by neutron stars. It will explore the exotic states of matter where density and pressure are higher than in atomic nuclei.

NICER will enable rotation-resolved spectroscopy of the thermal and non-thermal emissions of neutron stars in the soft (0.2–12 keV) X-ray band with unprecedented sensitivity, probing interior structure, the origins of dynamic phenomena, and the mechanisms that underlies the most powerful cosmic particle accelerators known.

NICER will achieve these goals by deploying, following launch in December 2016, an X-ray timing and spectroscopy instrument as an attached payload aboard the International Space Station (ISS). 

The National Center for Atmospheric Research (NCAR) is a North American federally funded research and development center devoted to service, research and education in the atmospheric and related sciences.

It is a non-profit association created in November 2003. The bodies of the association are the Management Board, the Supervisory Board and the Managing Director.

The Transiting Exoplanet Survey Satellite (TESS) is a planned space telescope for NASA's Explorer program, designed to search for extrasolar planets using the transit method.

The project is led by the Massachusetts Institute of Technology with seed funding from Google. In 2013 NASA announced that TESS had been selected for launch in 2017. TESS will be located on an High Earth orbit.

Mission concept

Once launched, the telescope would conduct a two-year all-sky survey program for exploring transiting exoplanets around nearby and bright stars. TESS would be equipped with four wide-angle telescopes and charge-coupled device (CCD) detectors, with a total size of 67 megapixels. Science data, which are pixel subarrays around each of up to 10,000 target stars per field, are transmitted to Earth every two weeks for further analysis. Full-frame images with an effective exposure time of two hours are transmitted to the ground as well, enabling astrophysicists to search the data for an unexpected, transient phenomenon, such as the optical counterpart to a gamma-ray burst.

Sentinel is a multi-satellite project to be launched from 2014, being developed by ESA under the Global Monitoring for Environment and Security (GMES) program, renamed as Copernicus program. The Sentinel missions include satellites radar and super-spectral imaging for land, ocean and atmospheric monitoring.

The Sentinel satellite familiy is designed to replace the ENVISAT mission.

Missions

The Sentinel missions will have the following objectives:

• Sentinel 1 will provide all-weather, day and night radar imaging for land and ocean services. The first Sentinel-1 satellite is planned for launch in 2014.
• Sentinel 2 will provide high-resolution optical imaging for land services (e.g. imagery of vegetation, soil and water cover, inland waterways and coastal areas). Sentinel-2 will also provide information for emergency services. The first Sentinel-2 satellite is planned for launch in 2014.
• Sentinel 3 will provide ocean and global land monitoring services. The first Sentinel-3 satellite is planned for launch in 2017.
• Sentinel 4, embarked as a payload upon a Meteosat Third Generation Satellite, will provide data for atmospheric composition monitoring. It will be launched in 2019.
• Sentinel 5 Precursor - subset of the Sentinel 5 sensor set planned for launch in 2015. The primary purpose of this was to provide overlapping data (especially SCIAMACHY atmospheric observations) with the aging ENVISAT. However contact with ENVISAT was lost in April 2012 and the mission was declared ended in May 2012. It is unknown whether Sentinel 5 Precursor will be rescheduled as a result.
• Sentinel 5 will also provide data for atmospheric composition monitoring. It will be embarked on a post-EUMETSAT Polar System (EPS) spacecraft and launched in 2020.
• Sentinel 6 is the intent to sustain high precision altimetry missions following the Jason-2 satellite.

NASA's Mars Exploration Rover Mission (MER) is an American robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars.

It began in 2003 with the sending of the two rovers—MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology.The mission's scientific objective was to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars. The mission is part of NASA's Mars Exploration Program, which includes three previous successful landers: the two Viking program landers in 1976 and Mars Pathfinder probe in 1997.

In July 2007, during the fourth mission extension, Martian dust storms blocked sunlight to the rovers and threatened the ability of the craft to gather energy through their solar panels, causing engineers to fear that one or both of them might be permanently disabled. However, the dust storms lifted, allowing them to resume operations.

On May 1, 2009, during its fifth mission extension, Spirit became stuck in soft soil on Mars.[5] After nearly nine months of attempts to get the rover back on track, including using test rovers on Earth, NASA announced on January 26, 2010 that Spirit was being retasked as a stationary science platform. This mode would enable Spirit to assist scientists in ways that a mobile platform could not, such as detecting "wobbles" in the planet's rotation that would indicate a liquid core.[6] Jet Propulsion Laboratory (JPL) lost contact with Spirit after last hearing from the rover on March 22, 2010 and continued attempts to regain communications lasted until May 25, 2011, bringing the elapsed mission time to 6 years 2 months 19 days, or over 25 times the original planned mission duration.

In recognition of the vast amount of scientific information amassed by both rovers, two asteroids have been named in their honor: 37452 Spirit and 39382 Opportunity. The mission is managed for NASA by the Jet Propulsion Laboratory, which designed, built, and is operating the rovers.
