SAG15

The general goal of the SAG15 Report was to collect and organize community input on key science questions for future imaging missions without focusing on specific mission architectures or assumed capabilities.

  • The international BepiColombo spacecraft will soon take flight, on a complex journey to the innermost planet of the Solar System, Mercury. Encompassing nine planetary flybys and travelling a total distance of nine billion km over a period of seven years, this will be one of the most intricate journeys ever flown by mission teams at ESA’s ESOC mission control centre.

  • How can I walk my dog on the Moon? What happens if I sneeze in space? Just some of the questions that more than 500 000 children around the world will be asking and attempting to answer over the next months, as part of this year’s FIRST LEGO League competition, a global STEM program with an annual theme that inspires and challenges young engineers and scientists. In Europe, ESA has teamed up with LEGO Education to provide inspiration, examples and expertise to the teams of children aged 6 to 16 who are competing for a place in the World Finals in...

  • The construction of ESA's Plato mission to find and study planets beyond our Solar System will be led by Germany’s OHB System AG as prime contractor, marking the start of the full industrial phase of the project.

  • A team of astronomers using the latest set of data from ESA’s Gaia mission to look for high-velocity stars being kicked out of the Milky Way were surprised to find stars instead sprinting inwards – perhaps from another galaxy.

  • ESA astronaut Alexander Gerst will take over the role of International Space Station commander from NASA astronaut Drew Feustel on 3 October. This marks the start of Expedition 57 and second half of Alexander’s Horizons mission.   With both Alexander and ESA astronaut Luca Parmitano set to command the International Space Station within the next 12 months, ESA astronaut Frank De Winne shares what it was like to be the first European in command.

  • From Lego-style satellites that plug together to robot avatars for lunar exploration, satellite maps for Arctic navigation to a DNA-analysing 'tricorder': next week 24 of planet Earth's top start-ups will showcase their cutting-edge ideas for space and beyond at the International Astronautical Congress in Germany.

  • As ESA celebrates the 100th launch of Ariane 5, the Agency’s worldwide ground station network is also marking ten years of providing vital tracking services to launchers soaring out of Kourou.

  • Using data from ESA’s Gaia stellar surveyor, astronomers have identified four stars that are possible places of origin of ‘Oumuamua, an interstellar object spotted during a brief visit to our Solar System in 2017.

  • Space Science Image of the Week: a monitoring camera on the BepiColombo Mercury Transfer Module takes a test image during pre-launch preparations

  • In this edition, Sentinel-2 takes us over the youngest country in the world: South Sudan

  • BepiColombo experts describe the mission to Mercury as the three spacecraft modules are assembled in launch configuration

  • The Copernicus Sentinel-1 mission returns images showing how oil is spreading in the Mediterranean Sea following a collision between two ships

  • Share your passion for space and organise your own European Space Talk for November 2018

  • Ian Regan, producer of the Titan segment of In Saturn's Rings, describes the meticulous process of creating the stunning visuals of this shrouded moon.

  • In short, a poster should be as close to an infographic as possible.

  • Fiscal year 2019 is here, but NASA doesn't have a new budget. Which programs could suffer the most as a consequence?

  • A collection of before and after slider images showing how views of planets in our solar system have changed over the years since NASA was created.

  • Planetary CEO Bill Nye issued the following statement from Homestead National Monument to celebrate the Total Solar Eclipse.

  • The U.S. National Park Service, The Planetary Society and CEO Bill Nye (The Science Guy®) are partnering to deliver a safe, inspiring and educational experience to kids, adults and families.

  • Bill Nye – The Science Guy® and CEO of the Planetary Society – will join park rangers and celebrated science educators as part of a three-day festival focused on the Total Eclipse of the Sun at Homestead National Monument of America in August.

  • The SDO.gsfc.nasa.gov website will be unavailable today from 7:00 am - noon ET while work on the electrical supply to the building takes place.

  • SDO will perform Station Keeping (or Delta-V) Maneuver #17 today between 2200-2250 UTC (6:00-6:50 p.m. ET). This maneuver is used to keep SDO inside its box in the geosynchronous belt. SDO thrusters will expel 82 grams of propellant to complete the maneuver. During the maneuver science data may be missing or blurry.

  • Today at 1500 UTC (11:00 am ET) SDO will perform the HMI roll. The spacecraft rolls once around the axis pointed towards the Sun to provide calibration information for the instruments. These measurements are also used to learn how round the Sun is. Here are other planned maneuvers through the rest of 2018. 07/18 @ 1945 UTC (3:45 pm ET) - Momentum Management #32 07/21 @ 0433 UTC (12:33 am ET) - Handover Season Starts with First Handover 07/25 @ 1230 UTC (8:30 am ET) - EVE Cruciform 08/08 @ to be determined - Simulated comet observation 08/12 @...

  • Today SDO is performing the EVE Field of View and HMI Flatfield calibration maneuvers. Between 1315 and 1910 UTC (9:15 am - 3:10 pm ET) SDO will move in patterns about the Sun. Science data may be unavailable at these times or blurry. Here is an AIA 193 Å image from 1354 UTC with the bottom right corner of the Sun cutoff by SDO pointing away from the center of the Sun.

  • Today, June 21, 2018, at 1007 UTC (6:07 am ET) the Sun reached its northernmost point in our sky. In the northern hemisphere we have the longest day of the year while people in the southern hemisphere have their longest night. Six months from now we will reverse places for the Winter Solstice. It's all due to the tilt of the Earth's rotation axis that tilts us toward the Sun in northern summer. Our ancestors often celebrated the Solstices with parties. I'll celebrate with some pictures of the Sun. For those who thought Solar Cycle 24 had faded into history,...
