Europa Spacecraft

Set to blast off sometime in the 2020s

This artist’s rendering shows NASA’s Europa mission spacecraft, which is being developed for a launch sometime in the 2020s. This view shows the spacecraft configuration, which could change before launch, as of early 2016.
The mission would place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of the giant planet’s moon Europa — a world that shows strong evidence for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life. The highly capable, radiation-tolerant spacecraft would enter into a long, looping orbit around Jupiter to perform repeated close flybys of Europa.
The concept image shows two large solar arrays extending from the sides of the spacecraft, to which the mission’s ice-penetrating radar antennas are attached. A saucer-shaped high-gain antenna is also side mounted, with a magnetometer boom placed next to it. On the forward end of the spacecraft (at left in this view) is a remote-sensing palette, which houses the rest of the science instrument payload.
The nominal mission would perform at least 45 flybys of Europa at altitudes varying from 1,700 miles to 16 miles (2,700 kilometers to 25 kilometers) above the surface.

Space news (The search for life beyond Earth) – An artist’s rendition of the Europa spacecraft orbiting Jupiter –

This 12-frame mosaic provides the highest resolution view ever obtained of the side of Jupiter’s moon Europa that faces the giant planet. It was obtained on Nov. 25, 1999 by the camera onboard the Galileo spacecraft, a past NASA mission to Jupiter and its moons which ended in 2003. NASA will announce today, Tuesday, May 26, the selection of science instruments for a mission to Europa, to investigate whether it could harbor conditions suitable for life. The Europa mission would conduct repeated close flybys of the small moon during a three-year period.
Numerous linear features in the center of this mosaic and toward the poles may have formed in response to tides strong enough to fracture Europa’s icy surface. Some of these features extend for over 1,500 kilometers (900 miles). Darker regions near the equator on the eastern (right) and western (left) limb may be vast areas of chaotic terrain. Bright white spots near the western limb are the ejecta blankets of young impact craters.
North is to the top of the picture and the sun illuminates the surface from the left. The image, centered at 0 latitude and 10 longitude, covers an area approximately 2,500 by 3,000 kilometers. The finest details that can discerned in this picture are about 2 kilometers across (about 1,550 by 1,860 miles). The images were taken by Galileo’s camera when the spacecraft was 94,000 kilometers (58,000 miles) from Europa.

NASA’s Jet Propulsion Laboratory released this artist‘s rendering of the Europa spacecraft, which is set to head to Jupiter sometime in the 2020s. The Europa Mission spacecraft configuration in early 2016 is shown in this image. The final spacecraft configuration at launch could easily be different, so stay tuned here for more news. The position of Jupiter in the sky relative to Europa and the spacecraft are also off in this drawing. 

This is an artist’s concept of a plume of water vapor thought to be ejected off the frigid, icy surface of the Jovian moon Europa, located about 500 million miles (800 million kilometers) from the sun. Spectroscopic measurements from NASA’s Hubble Space Telescope led scientists to calculate that the plume rises to an altitude of 125 miles (201 kilometers) and then it probably rains frost back onto the moon’s surface. Previous findings already pointed to a subsurface ocean under Europa’s icy crust.

Two large solar arrays are shown extending from the sides of the Europa spacecraft to which the ice-penetrating radar antennas are attached in this artist’s rendition. On the side of the craft, a saucer-shaped high gain antenna is depicted next to a magnetometer boom. On the forward section is a remote-sensing palette with the remaining science instruments.

Jupiter’s moon Europa has a crust made up of blocks, which are thought to have broken apart and ‘rafted’ into new positions, as shown in the image on the left. These features are the best geologic evidence to date that Europa may have had a subsurface ocean at some time in its past.
Combined with the geologic data, the presence of a magnetic field leads scientists to believe an ocean is most likely present at Europa today. In this false color image, reddish-brown areas represent non-ice material resulting from geologic activity. White areas are rays of material ejected during the formation of the Pwyll impact crater. Icy plains are shown in blue tones to distinguish possibly coarse-grained ice (dark blue) from fine-grained ice (light blue). Long, dark lines are ridges and fractures in the crust, some of which are more than 1,850 miles long. These images were obtained by NASA’s Galileo spacecraft during Sept. 7, 1996, Dec. 1996 and Feb. 1997 at a distance of 417,489 miles.

The Europa Mission profile has a very capable, radiation-resistant spacecraft traveling to Jupiter, where it enters into a long, looping orbit of the giant planet in order to perform at least 45 repeated flybys of Europa at altitudes ranging from 1700 miles to 16 miles (2700 kilometers to 25 kilometers) above its surface. Planetary scientists want to take a closer look at the evidence for an ocean of liquid water beneath its icy shell. An ocean of liquid water that could be the habitat of alien lifeforms we want to get to know better.

NASA’s Juno Spacecraft Makes Jupiter Orbit After Five Years Traveling Across the Solar System

Juno team still celebrating confirmation of successful insertion into Jupiter orbit

Space news (Space missions to Jupiter: NASA; Juno makes orbit around mighty Jupiter) – 370 million miles (596 million kilometers) from Earth, traveling at around 11 miles per second (17 kilometers per second) relative to the Sol, or 29 miles/second (46 kilometers/s) relative to Earth –

It’s a bold, confident step forward into the solar system for NASA and the human journey to the beginning of space and time. After traveling nearly 1.36 billion miles (2.2 billion kilometers) during a journey lasting almost five years, NASA scientists and engineers prepared the Juno spacecraft for a planned 45-minute main engine burn to slow the spacecraft by around 1,200 mph (540 meters per second). At this lesser speed, the spacecraft falls quietly into mighty Jupiter’s gravity well, by entering Jupiter orbital insertion at a more controlled velocity. During this pre-insertion phase mission, specialists in NASA’s Jet Propulsion Laboratory in Pasadena, California altered Juno’s altitude to point its main engine in the right direction for the maneuver. They also increased the spacecraft’s rate of rotation from 2 to 5 revolutions per minute (RPM) to help stabilize it.

“Independence Day always is something to celebrate, but today we can add to America’s birthday another reason to cheer — Juno is at Jupiter,” said NASA administrator Charlie Bolden. “And what is more American than a NASA mission going boldly where no spacecraft has gone before? With Juno, we will investigate the unknowns of Jupiter’s massive radiation belts to delve deep into not only the planet’s interior but into how Jupiter was born and how our entire solar system evolved.”

At 8:18 p.m. PDT (11:18 p.m. EDT) on Monday, June 4, 2016, NASA’s Juno spacecraft started its 645-Newton Leros-1b main engine to decrease velocity to allow for a safe Jupiter orbital insertion. 35 minutes later, at 8:53 p.m. PDT (11:53 p.m. EDT), NASA’s Juno team received data from the spacecraft confirming a successful insertion into orbit around mighty Jupiter. A little earlier than expected, but better early, than never at all.

“This is the one time I don’t mind being stuck in a windowless room on the night of the 4th of July,” said Scott Bolton, principal investigator of Juno from Southwest Research Institute in San Antonio. “The mission team did great. The spacecraft did great. We are looking great. It’s a great day.”

After the successful Jupiter orbital insertion, the team turned Juno so its three huge solar arrays, shaped like a windmill, could capture the sun’s rays on 18,698 individual solar cells that give Juno its energy. At an average distance of around 484 million miles (778 million kilometers) from Sol, Jupiter is generally five times further from the sun than Earth, which means the amount of solar energy collected by Juno’s solar array’s about 25 times weaker. At this distance, despite recent advances in solar cell technology, Juno’s solar collectors only provide about 450 watts of power, enough to power four household light bulbs. 

“The spacecraft worked perfectly, which is always nice when you’re driving a vehicle with 1.7 billion miles on the odometer,” said Rick Nybakken, Juno project manager from JPL. “Jupiter orbit insertion was a big step and the most challenging remaining in our mission plan, but there are others that have to occur before we can give the science team members the mission they are looking for.” 

Next, the team will prepare Juno to conduct the science data collection phase of the mission. They need to do final testing of all spacecraft subsystems, calibrate science instruments, and collect some data to enable the next phase of Juno’s mission to Jupiter.

“Our official science collection phase begins in October, but we’ve figured out a way to collect data a lot earlier than that,” said Bolton. “Which when you’re talking about the single biggest planetary body in the solar system is a really good thing. There is a lot to see and do here.” 

The Juno mission’s primary science objective is to uncover clues to the origin and evolution of mighty Jupiter, the biggest planet in our solar system. Now, Juno will turn its suite of nine science instruments to the task of exploring the possible existence of a solid planetary core and mapping the gas giant’s extreme magnetic field. It will also measure the amount of water and ammonia in the deep atmosphere of Jupiter and observe its amazing, stunning auroras. If the mission goes as scripted, human knowledge and understanding of the birth and formation of giant planets will take a huge step forward, and the part Jupiter played in the origin and evolution of the solar system and life on Earth could be partly revealed. The knowledge we gain through our journey to Jupiter can even offer us useful, critical clues to the processes creating some of the bizarre creatures in the Planetary Zoo of Exoplanets.

For millennium Jupiter was but a wandering star until Galileo observed transiting bodies change position with respect to the suspect star over the course of a few nights. Through these observations, he realized these bodies were moons orbiting a distant planet. He came to the revelation the Earth isn’t the center of the universe and forever changed the way we view our place in the cosmos.

Jupiter’s Opposition

Space & astronomy wiki – the planets in the solar system –

Jupiter’s opposition

Is when Earth passes more or less between the Sun and Jupiter, placing mighty Jupiter opposite the Sun in our sky

The opposition of Jupiter occurred on February 6 in 2015. On this date, Jupiter came to within 404 million miles of Earth (650 million km), the closest opposition until 2019.

The opposition of Jupiter occurs on March 8 in 2016. Jupiter comes into opposition every 13 months, which is the amount of time it takes Earth to travel once around the Sun relative to Earth.
