It covers the period between and But quirks of ocean currents , rising or falling coastlines, and even gravity itself mean sea-level change is not uniform across the planet. The SEA tool combines data from satellite measurements, tide gauges , and other land and sea-based observations and products. Webb launched on the sun-facing side of the Earth and travels on a slightly curved path so Webb's "distance travelled" is greater than its altitude.

Temperature control is a vital aspect of Webb's design, engineering and operations. Of the many temperature monitoring points on the observatory, this page displays 2 "hot side" and 2 "cold side" temperatures that are a good indication of overall temperature status and trends.

The temperatures displayed on the hot side of the observatory are located on the sunshield structure and spacecraft bus. The temperatures displayed on the cold side of the observatory are located on the primary mirror and instrument ISIM module radiator. They are labelled with the following letters note: these labels will pop up if you hover your mouse over the display :. There are many more temperature sensors on the observatory that our engineers monitor throughout the deployment, commissioning and operations processes.

The data points shown here give a good overall indication of the temperature trends on each side of the sunshield as we move through deployment and commissioning. They illustrate the great contrast between the hot and cold sides of the spacecraft and the incredible engineering and effectiveness of the sunshield. These temperature observations are reported daily from actual spacecraft telemetry data. Temperature values will continue to be reported in the months that follow the completed deployment as the spacecraft cools to operational values.

But Webb never actually arrives at L2, it is travelling to enter an orbit around L2. Webb's L2 orbit is very large in size and it enters its orbit before it reaches the linear distance between Earth and L2.

Webb's orbit around L2 is known as a halo orbit which, rather than a single path, is an orbit that periodically varies through a series of paths around L2. By design, the launch vehicle and Webb's trajectory put Webb on a path to an L2 orbit with only small inputs needed to refine it.

Currently not available in Titan or Icy Moons Trek. Pick a feature or area that you would like to 3D print, and we'll give you the file! A few of the portals - Bennu , Ceres , Ryugu , and Vesta - have pre-generated 3D print files of the entire globe.

Explore the Moon, Mars, and Vesta in 3D. Spin our moon, the Red Planet or the huge asteroid around its axis, orient it whichever direction you want, and approach from any angle. Change the projection or view by clicking the globe or '3D' button located at the bottom-left of any Trek. Draw a straight line, a polyline, or freehand your own proposed rover traverse, and we'll give you the distance. It may look tiny on the map, but you'll be amazed how huge or small these celestial bodies are.

Draw your line, polyline, or freehand polyline and let us do the calculation. Draw a line, polyline, or freehand polyline and see how the elevation changes.

We extract the elevation profile from a digital elevation model DEM of the terrain and give you the results in an interactive graph. If you would like to see numbers in a convenient format, simply export the elevation profile to a.

Note: The GIF shows an older version of our elevation profiler. The current one, which you can access on the respective Trek sites, works in the same way AND has a nifty zoom feature. Try it out and let us know what you think in the Feedback link below. Select 'Calculate Sun Angle' from the Tool menu then place your marker.

Choose the start and end dates and times, set your interval and submit. The default interval is set to 50 and will display 50 data points interspersed equally between the start and end time. The lower the number, the less accurate the results because the less frequent the readings. The results are given in a graph showing the Elevation and Azimuth of your placed marker to the sun. Through this service, you can display map layers from Treks on your software system. Experience Earth and our solar system, the universe and the spacecraft exploring them, with immersive apps for Mac, PC and mobile devices.

One of the niftiest app features is the Asteroid Watch option. It gives the next five closest approaches of near-Earth objects NEOs along with a visualization that shows how far from our planet they will pass. Eyes on Asteroids contains layers of NEO information, enough to entertain and enlighten you for hours.

With twice-daily updates, you can also learn about new asteroids and comets as they're spotted and added to NASA's database.
