The Falcon 9 launch vehicle also delivered the SpaceIL Beresheet craft — the first privately funded lunar lander — to space as well as the experimental U.S. Air Force Research Laboratory (AFRL) S5 smallsat to orbit.

Deployments occurred at approximately 33 and 44 minutes after liftoff.

The Falcon 9 rocket’s first stage for this mission had previously supported the Iridium-7 mission in July of 2018 and the SAOCOM 1A mission in October of 2018.

Following stage separation, SpaceX landed Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which was stationed in the Atlantic Ocean.

The C- and Ku-band transponders aboard this satellite will be used for voice, data and video distribution throughout Indonesia.

The U.S. Air Force’s Air Force Research Laboratory (AFRL) brought their experimental smallsat to this launch as a rideshare payload. Known as the S5, this smallsat was developer and integrated by Blue Canyon Technologies and is scheduled for a mission lasting one year.

Israeli nonprofit SpaceIL and Israel Aerospace Industries (IAI) announced Beresheet communicated for the first time with the mission’s control center in Yehud, Israel, at 9:23 p.m. ET and the spacecraft’s legs deployed two minutes later.

Once Beresheet (“in the beginning”) completes its lunar mission, Israel will join superpowers China, Russia and the United States in landing a spacecraft on the moon.

The spacecraft successfully disengaged from the SpaceX Falcon 9 at around 60,000 kilometers above Earth’s surface, and started, under is own power, a two-month voyage to the Moon’s surface.

Comtech expands X/Y antenna product family to the LEO/MEO and HAPS markets

Comtech Command and Control Technologies has introduced a new line of transportable, full motion antennas for tracking Low Earth Orbit (LEO), Medium Earth Orbit (MEO) satellites and High Altitude Pseudo-Satellites (HAPS).

The Micro Deployable X/Y Tracking Antennas use the same two-axis pedestal technology and control software used on Comtech’s larger X/Y systems, thereby eliminating the keyhole at zenith, cable wrap, and backlash problems found on traditional El/Az tracking antennas.

These advantages of the X/Y design are now offered in small and lightweight packages.

This cost effective, full hemispheric coverage solution set can be transported on a commercial airliner and can be assembled for operation by one individual in less than 30 minutes — without the need for any special equipment.

The Micro Deployable X/Y Tracking Antennas come in three sizes:

• Series A that can hold 30 to 60cm reflectors
• Series B that can hold 80 to 1.2m reflectors
• 
Series C that can hold 1.4 to 1.6m reflectors.

Comtech offers the antenna systems in single and multi-band frequencies from L-band to Q-band.

The antenna includes a GPS system that provides precision time and terminal position, and pointing accuracy is better than 0.1 degree.

With a flexible system configuration, low power consumption and high reliability, the Micro Deployable X/Y Tracking Antennas include Ethernet (TCP/IP) remote control for monitoring and control based on a Linux operating system.

Additional features include a TLE-based program track satellite scheduler and precision carbon composites reflectors.

This system does not require significant maintenance.

The introduction of the Micro Deployable X/Y Terminals caps a successful year of market expansion for the industry’s most extensive and mature line of X/Y antenna systems, as well as a full range of high wind rated radomes.

Comtech will continue to bring highly reliable and innovative products to the smallsat LEO/MEO and HAPS markets.

Comtech Command and Control Technologies of Annapolis, Maryland, is a wholly owned subsidiary of Comtech Telecommunications Corporation of Melville, New York.

Comtech’s Space and Component Technology (SCT) division of Cypress, California, has specialized for 42 years in providing ground system services in the form of turn-key site development, infrastructure, operations and maintenance of several range tracking stations in the South Pacific.

Over the past 16 years, SCT added an extensive line of LEO/MEO X/Y tracking antennas for the industry.

Using the concept of product families and platform-based product development to increase variety, shorten lead-times, and reduce costs without compromising system performance, Comtech is able to offer a product range with generic ‘family’ features from 30 cm to 13 meter apertures, to include autotracking systems as well as a range of deployable, trailer mounted, or fixed systems.

GOES-17 now operational to serve as NOAA’s primary Pacific weather satellite

GOES-17 is operational as NOAA’s GOES West satellite — the satellite will serve as NOAA’s primary geostationary satellite for detecting and monitoring Pacific storm systems, fog, wildfires, and other weather phenomena that affect the western United States, Alaska, and Hawaii.

The latest milestone for GOES-17 comes exactly 11 months after the satellite first reached its geostationary orbit 22,000 above Earth.

Launched March 1, 2018, GOES-17 is NOAA’s second advanced geostationary weather satellite and the sister satellite to GOES-16 (also known as GOES East). Together, the two satellites provide high-resolution visible and infrared imagery as well as lightning observations of more than half the globe — from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle.

GOES-17 has already been helping forecasters track the weather and other environmental hazards in places such as California, Alaska and Hawaii.

The satellite began transmitting its first images from its new orbital position in November of 2018.

Since then, forecasters have been using GOES-17 data to see weather forming over the northeastern Pacific Ocean, where many weather systems that affect the continental U.S. first form.

Until recently, high-quality data coverage of the Pacific Ocean was sparse. Now that GOES-17 data is available, forecasters have access to more detailed views of high-impact weather systems and other environmental hazards such as wildfire smoke and volcanic ash.

For example, GOES-17 helps forecasters predict the intensity and impact of Pacific storms that hit the West Coast. These include atmospheric river events that bring heavy rain and high-elevation snow to California and the Pacific Northwest, especially during the winter months.

In Hawaii and the central Pacific Ocean, GOES-17’s high-resolution visible and infrared imagery will improve hurricane forecasts and allow meteorologists to better predict areas of intense rainfall. In 2018, Hawaii set a new national rainfall record when 49.69 inches of rain fell in 24 hours. The state also faced several tropical weather threats in what became an active hurricane season in the Central and Eastern Pacific.

Forecasters in Hawaii and other remote territories like the Marshall Islands and American Samoa are also now able to track thunderstorms in real-time.

The Geostationary Lightning Mapper (GLM) on-board GOES-17 helps forecasters determine when thunderstorms and convective weather events are intensifying or becoming more dangerous. In 2018, the National Weather Service began using GLM data to issue severe thunderstorm warnings and keep the public out of harm’s way.

East and West satellites. Image is courtesy of NOAA.

Among the benefits of GOES-17’s high-resolution and rapid-scan capability is the satellite’s ability to detect wildfires and monitor smoke coverage in near real-time.

The dry climate of the western U.S. makes the region especially vulnerable to wildfires. In 2018, for example, California faced one of its deadliest and most destructive wildfire seasons on record.

Providing high-definition images as often as every minute, GOES-17 helps forecasters distribute critical information to firefighters and emergency managers that saves lives.

Additionally, real-time imagery of smoke plumes from fires also improves air quality forecasts.

stands out even when other clouds are nearby.

GOES-17 has been especially valuable to Alaska, where NOAA’s older geostationary satellites provided far less coverage.

The state’s vast territory and sparse population mean that Earth-based observations from radar, aircraft and buoys, are limited. The satellite’s combinable image channels (known as “multi-spectral imagery”) help forecasters distinguish between clouds, snow-covered ground and sea ice around Alaska’s coasts.

These advanced imaging capabilities mean safer, more accurate aviation and shipping forecasts, especially during Alaska’s long, dark winter months, when visible satellite imagery is less useful.

Fog and icy conditions often cause flight delays and impact airport operations.

At Ted Stevens International Airport in Anchorage, fog occurs almost daily during winter.

Island on January 15, 2019. Image is courtesy of NOAA.

The airport is the second-busiest cargo airport in the U.S. and fourth-busiest in the world, which makes understanding the timing of fog and low clouds especially important.

Just as GOES-16 data helped airlines mitigate flight delays at San Francisco International Airport in early 2017, GOES-17 data will help forecasters to predict when fog will form and clear with much greater accuracy.

Among GOES-17’s many benefits to Alaska is the satellite’s ability to track volcanic ash clouds.

Data from GOES-17 makes it easier to determine the site of an eruption, as well as the height and direction in which an ash cloud is moving.

Forecasters share this information with other agencies, such as the Alaska Aviation Weather Unit and the U.S. Geological Survey’s Alaska Volcano Observatory to issue volcanic ash advisories and other warnings to keep air travel safe.

Now that the satellite is operational, GOES-17 replaces GOES-15 as NOAA’s GOES West satellite. The latter entered service in December of 2011.

However, due to technical issues with GOES-17’s Advanced Baseline Imager — or ABI, the satellite’s main instrument — GOES-15 and GOES-17 will operate in unison until early July 2019.

The overlap will allow scientists and engineers to make sure that GOES-17 is performing adequately before the older GOES-15 satellite gets placed in storage as a backup.

According to Dr. Stephen Volz, the Director, NOAA’s Satellite and Information Service, the GOES-17 ABI is now projected to deliver more than 97 percent of the data it was designed to provide.

Michael Ottenweller, a National Weather Service forecaster at the Anchorage, Alaska field office, said that in his nearly six years forecasting here, he has never seen a product revolutionize the ability to forecast the way GOES-17 has — the advent of GOES over this domain makes forecasting tangibly easier and better. Now, not only is there reliable data, but that data can be looped. This changes everything. The GOES constellation will continue to meet the needs of forecasters across the country.
