The Department of Homeland Security’s (DHS) Cybersecurity and Infrastructure Security Agency (CISA) has issued a memo to election officials and digital voting providers warning them of “significant security risks" posed by online voting, CyberScoop reported Monday.

The return of ballots online by voters “faces significant security risks to the confidentiality, integrity, and availability of voted ballots,” CISA said in the advisory. “These risks can ultimately affect the tabulation and results and, can occur at scale.”

The Federal Bureau of Investigation (FBI), National Institute of Standards and Technology (NIST) and the Election Assistance Commission signed off on the DHS memo.

“[W]e recommend paper ballot returns as electronic ballot return technologies are high-risk even with controls in place,” the agencies said in a joint statement. “Election officials are best positioned to evaluate the risks and make decisions accordingly.”

Rep. Jim Langevin (D-R.I.), a House Homeland Security Committee member, called on CISA to publicly release the document to better inform the voters of the potential risk associated with internet-connected voting. “Our intelligence community has warned that malicious state actors such as Russia are trying to interfere in our elections, and we must heed the recommendations of the experts at CISA to bolster our systems,” he said in a statement.

Pam Underwood, director of the Federal Aviation Administration’s (FAA) Office of Spaceports, has said that her office is working with the U.S. Space Force to update management procedures for East and West-Coast ranges, SpaceNews reported Friday.

Underwood told attendees at a recent Global Spaceport Alliance meeting that the new office is developing an infrastructure grant plan for spaceports as well as revised launch and reentry regulations and other commercial launch promotion efforts.

“These are detailed activities that we take very seriously,” she said. “We’ve been able to talk with spaceports and get feedback about how this is impacting their daily activities and some of the economic and operational implications.”

The FAA recently established the Office of Spaceports in line with the Office of Commercial Space Transportation's (AST) reorganization plans and a 2018 reauthorization bill to improve licensing procedures as well as the commercial space transportation industry.

Underwood’s comments come after AST issued a launch site operators license to the Titusville-Cocoa Airport Authority to authorize space launches from Space Coast Regional Airport in Florida.

Air Force Life Cycle Management Center’s Metal Technology Office uses a variety of technologies to replace aircraft parts and support repair operations across the force.

The office's team applies additive manufacturing, heat treatment, welding and other methods to help repair teams maintain aircraft, Wright-Patterson AF Base said Friday.

“We are the subject matter experts for the Metals Technology career field, which involves additive manufacturing, machining, welding, heat treating, parts repair and fabrication,” said Che Dacalio, an engineering technician at the office.

Dacalio's team visits U.S. sites to look at the work of metal technology shops and deliver needed training. Major U.S. commands have a total of about 190 MT shops.

"We seek to maximize MT Shop utilization to sustain continuous Air Force flight and improve mission generation by supplying parts on demand, anytime, from almost any Air Force installation and at a fraction of the costs when compared to similar contracted efforts," the engineer added.

For example, the office helped U.S. Air Force Academy model an already-obsolete spinner backing plate of a T-51 trainer aircraft. Afterward, Dacalio arranged with an MT shop at Luke Air Force Base for the local production of new spinner backing plates.

Maj. Cody Chiles, spokesperson for the Combined Force Space Component Command, said the U.S. Space Force is monitoring the reentry of a Chinese Long March 5B rocket into the Earth's atmosphere, Spaceflight Now reported Saturday.

Chiles told the publication that the Space Force’s 18th Space Control Squadron is heading tracking activities for the 100-foot rocket’s core stage as it facilitates an unguided reentry after a week in orbit for a crew capsule mission.

The rocket, which was maneuvering around Earth in an elliptical orbit on Saturday, is expected to be the largest object to conduct an unguided reentry in decades, the report states.

According to the Aerospace Corp., reentry prediction errors of at least one minute could have critical impacts such as discrepancies in debris locations.

The United States and the Czech Republic have agreed to assist each other as both countries are implementing the use of 5G networks for public and economic applications. Both countries made this agreement last Wednesday as a joint declaration.

The partnership aims to support cross-border commerce and services, fortify the connection between global economies and secure communications networks of both nations from interference, the U.S. Embassy in Czech Republic said Thursday.

The agreement also constitutes assessments on supplier transparency, corporate ethics and commitment; and whether network suppliers are improperly under foreign influence. The U.S. and the Czech Republic also plan to further discuss and promote 5G security in NATO.
